Ah! 7-20 here. Do we have different revisions of the manual, perhaps? :)

So, the numbering of the interrupts is not derived from anything but
the "Name" field in those tables? 0 1 3 would be Slice Timer 0, 1 0 3
would be Slice Timer 1 (main, interrupt 0, we always use 3 on Efika
for some reason) and 1 9 3 would be TMR0? PCI control and initiator
interrupts would be 2 (8,9,10) 3?

Well, this certainly makes a lot more sense, at least in terms of
deriving the numbers, however it looks like it's a fairly nonsensical
numbering system to be fair.
